Insufficient nighttime sleep among infants and preschool-aged children could be a risk factor in the development of childhood obesity. Napping does not appear to be an adequate substitute for nighttime sleep. Researchers studied close to 2,000 children...
A study shows that teens who sleep less than eight hours a night eat higher proportions of snacks. This suggests that short sleep duration may increase obesity risk by causing changes in eating patterns. For each one-hour increase in sleep duration, the...
A new study suggests a sleep-deprived mind can be kept alert by hunger. The research examined the effects of starvation on fruit flies that had been genetically engineered to be sensitive to sleep deprivation. Flies deprived of food stayed awake longer...
Your hair follicles hold a record of the gene activity that influences when you wake and sleep. This fact could be used to diagnose and study sleep disorders. Your sleep-wake cycle is partly controlled by so-called clock genes. These genes vary their...
According to new research, the effects of chronic sleep deprivation on your brain are similar to those of acute sleep deprivation. Researchers found that in rats, five consecutive nights of only four hours of sleep had the same effect as just one night...
Helping kids get a good night's sleep often comes down to technique. Avoiding late-night technology use and keeping a regular sleep schedule are two important techniques to heed as kids head back to school. Recent studies found that adolescents used multiple...
Disruptions to your normal sleep cycle, such as pulling several all-nighters, could lead to an increase of triglycerides in your blood. High levels of triglycerides in the blood are a risk factor for heart disease and obesity. The new findings could have...
The bad news, at least according to the Washington Post article linked below, is that it's fairly hard to find foods that help with sleep. There is, however, and easier question -- what foods should you avoid? A study that tracked the diets and sleep...
A new study shows that a sleep disorder may be a sign of dementia or Parkinson’s disease up to 50 years before the disorders are diagnosed. Researchers identified people who experienced rapid eye movement (REM) sleep behavior disorder for at least 15...
New research shows that middle-aged and older women who have trouble falling or staying asleep are also more likely to gain weight. The findings strengthen the evidence that sleep problems are related to weight gain. The study design allowed the researchers...
Academic grades of children and teens with obstructive sleep apnea are worse than those of students who do not suffer from sleep-disordered breathing. In a recent study, moderate to severe obstructive sleep apnea was linked to both lower academic grades...
Long sleep duration is associated with an elevated prevalence of metabolic syndrome in older adults. Study participants who reported a habitual daily sleep duration of eight hours or more, including naps, were 15 percent more likely to have metabolic...
Highly variable sleep schedules predict an elevated risk for suicide. The correlation is independent of depression. A sample of actively suicidal undergraduate students had a delayed mean bedtime of about 2 AM, restricted total sleep time of 6.3 hours...
Some nurses struggle to remain vigilant during successive 12-hour shifts. Lapses of attention among such nurses ranged from zero to 48 lapses per vigilance test. Although half of nurses committed no more than one lapse, 10 percent of nurses had nine or...
Color perception slowly goes off-kilter during wakefulness and is restored during sleep, new research suggests. Results of a study indicate that wakefulness causes people to classify the color gray as having a slightly but significantly greenish tint...
